[@rickmaudlin2160]

Two ideas for your consideration: 1. 2 LED (or other) indicators showing if either/or both alerts had been activated. Manually re-setable. 2. A latching dry contact closure for external alarm monitoring and/or rapid activation of circuit disconnects. Both would be useful if your away from the site. ie you come home and some electronics are not working correctly. Thanks for your work and training.

[@disasterprepper]

Hi Rick, thanks for the suggestions. The current design does have LEDs to indicate when an alarm condition is detected. But believe me, the audible alarm will leave no doubt. They reset automatically when the condition goes away. We did discuss making it a latched output, but this first version doesn't have that. The ability to drive an external system is also something we discussed, but again, it wasn't done in this first unit.

[@richardmcalister1911]

Thank you for making this capability available for the ordinary person. I'm a retired Minuteman III Missile Combat Crew Commander and I still remember the white EMP light which would illuminate on my console following a simulated nuclear detonation (nudet). I'm looking forward to having this technology in my home. (564th SMS & 400th SMS)

[@firevr]

This is brilliant, as a firefighter and electrician with an MSc Disaster and Emergency Planning and Management, I have considered all sorts of tech solutions to such problems. I absolutely love this solution! If you don’t mind, I have a few thoughts… consider two versions one for the USA and a 230v version for the UK and Europe. Build this into consumer units (fuse boards) and have it become the main switch, still giving an audible warning but also opens itself (the main switch). Users will have no action to take at home, and any desired solutions requiring Bluetooth, internet, sms etc… to advise users while away from home are not required. Also, if home automation platforms could advise of total power loss via their apps, maybe that would provide enough of a heads up to allow users at work to throw their iPhones and small devices into protective containers

[@jklep523]

[@life-longpatriot8258]

Another suggestion: a different tone for the airburst alert vs. the power spike/drop on the line alert.

[@disasterprepper]

The E1/E2 pulse causes a single roughly 2-second alarm. The E3 power line disturbance causes either a sustained beep-beep-beep or a solid beeeeeep. It's very easy to tell them apart.

[@BluRidgePrepper]

[@roadhammmer]

Additional mabe add like a push button braker that it shorts to trip it along with the ability to throw a disconnect. So when you come in form working outside you can look at the device and see what braker is poped out as a indicator.

[@guyloughridge4628]

Arthur, Please be sure to add a second LED that stays latched on, and continues to make a sound. That second LED should be labeled "EMP Pulse Detected". This is needed because the device might not be nearby or even heard (thus we would miss the alert).

[@disasterprepper]

The way things would occur is that when the EMP goes off, the unit will sound (and light) for about two seconds. Then as voltage levels rise on the power lines, perhaps a minute later, the unit will sound (and light) again and stay on until the voltage level lowers (likely when the grid comes down). While I understand the utility of a latched output, it probably wouldn't be terribly helpful since the entire event will be over in minutes (perhaps an hour at most). If you suddenly came home but had missed the E1/E2 pulse alarm, the E3 alarm would turn and stay on as soon as the voltage rose more than about 30 volts.

[@engineer775]

Great job as always! I too would love to review it and offer this to our customers.

As you were mentioning the Low voltage alarm function, I realized that this function would be handy when running a portable generator. If a thief were to remove it, the alarm would sound. Living in the PNW, I've heard the stories of generators being stolen with the thieves starting the victim's lawn mower to cover for the missing sound of the generator.

[@helloworld8136]

Could you add a relay so that once the power surge is detected your device activates the relay which would essentially short out in the outlet automatically tripping the breaker for that circuit in the house.

[@disasterprepper]

It's possible, but shorting out a breaker might require 10 times the rated current. That means you'd need to pull perhaps 150 amps, which can be tricky to do safely.

[@bernardpritchard4535]

In electronics, that's called a "crowbar" circuit, and it is commonly used in things like fast-switching power supplies. You wouldn't want to use one on your house though, because if your home circuit breakers are sticky at all, it lights the house on fire. :-))

Awesome and exciting product. If some energy spikes are so short in duration, how would you have time to get to your service panel to open / disconnect the main breaker?

[@disasterprepper]

You wouldn't have time to do anything about E1 or E2 other than surge suppress them. The are over in microseconds. But E3 can last minutes or even hours, and that's what's most likely to cause damage to a home or business.

[@bondscalper]

How much warning do you get ?? Minutes or seconds??

[@disasterprepper]

You'd be warned of E1 and E2 as it happened with a short alarm. Then as E3 caused the power lines to rise, the alarm would become continuous. E3 can last minutes or even hours.

[@gregorythomas333]

I use a contactor for my computer room power...how hard would it be for this unit to have the alarm pull a relay high (or low) to automatically disconnect the power to the room? Maybe even something as simple as a signal to an Arduino so it can fire the relay which in turn shuts down the contactor? Also sometimes my grid power can occasionally dip as low as 105VAC during the high temp summer months...can the low alarm be adjusted to compensate for that? Sorry to ask so much but my computer systems are worth a lot to me and I want to protect them as well as possible.

[@disasterprepper]

Hi Greg, good to hear from you. We have looked at creating an auto-trip device sort of like what you're describing. It's not really difficult, but there are some complications once you start messing with the flow of power into a home or business. I suspect we will develop something like that, but for now, this is a very useful warning device. As for the 105 VAC, that should be okay. This unit current trips a little below that, but wait and ask me again once the final production units are shipping.

[@kristovatlas]

Do CMEs and EMP events typically have a long "warm-up" time during which this will be triggered and you can rush to your breaker box to sever the connection? My understanding was that they quickly spike to equipment-damaging levels within milliseconds of the initial surge, and this window of opportunity for a human to react simply doesn't exist.

[@disasterprepper]

The E1 and E2 will be over in microseconds, but the E3 surge (which is what is most likely to cause damage to things plugged in) occurs over minutes to hours.

QUESTION 1. Wouldn't the power surge already be at the breaker box in order to "sound the alarm"? If so, I'm likely not going to be effective fast enough at throwing the main breaker (as well as on my Generac breaker panel too) because mine are located in the basement. 2. According to EMP Shield, their devices would automatically protect the home and the generator without me doing anything. Have you ever tested their product for effectiveness? If not, is there any reason you would doubt their effectiveness? Thank you!

[@disasterprepper]

The E1/E2 pulses will occur in microseconds, so the unit will just tell you that they just happened. The E3 could take minutes to cause the power lines to rise to dangerous levels. As the voltage rises, the EMP Alert sounds an over or under voltage alarm to let you know that the power levels are moving outside normal operating ranges.

[@or6060]

isnt this basically a really strong surge protector that beeps?

[@disasterprepper]

It's not actually a surge protection device. Rather, it detects various conditions associated with EMPs and CMEs and sounds an alarm.

[@tmt8425]

If you look at his products site he does have a commercial whole house surge protector he recommended made by a third party and he has videos about it. I had an electrician install mine. There are instructions but I did not want to DIY my circuit breaker panel. Other surge protectors won’t trip fast enough to stop damage. That is my understanding.

Question: Would this alarm then work in a generator outlet? After a yet to be determined amount of time, I'll be uncovering my generator from the shielding fabric cover I made, and plugging this into it. I'm sure that my box store generator doesn't produce a perfect sine wave. Thanks.

[@disasterprepper]

Yes, it would, but instead of detecting E3 on the power lines, it would be detecting overvoltage and undervoltage conditions on the generator output. The pulse detection would still work the same.

[@Devin82m]

Questions: 1. Will it go off for lightening strikes either nearby or directly? 2. I thought the EMP pulses happened very quickly, hence the nano second response time of the surge protector you suggest, is that true?

[@disasterprepper]

1. It shouldn't. The pulse response is optimized for very fast impulses, much faster than lightning. 2. The E1 occurs in nanoseconds, the E2 in microseconds, and the E3 in minutes to hours. This devices warns when E1/E2 occurs, as well as when E3 is occurring, giving you time to hopefully avoid the harmful E3 damage.

[@kristovatlas]

@@disasterprepper How likely are E1/E2 to damage equipment vs E3?

[@KumiOriFarm]

Wouldn't it be too late when the alarm goes off? How much time would I have after the alarm sounds to throw the main breaker?

[@disasterprepper]

You'd be warned of E1 and E2 as it happened with a short alarm. Then as E3 caused the power lines to rise, the alarm would become continuous. E3 can last minutes or even hours.

[@tmt8425]

Based on some other answers Arthur gave to questions, this is what would happen. If an E1 or E2 event occurs, you do not have time to do anything bc it will be over in a millisecond. However, an EMP can go off far enough from your home that you don’t experience the effects of E1 or E2. However, those events , are escaped the third thing to be concerned about is that the pulse will travel from the electrical grid and wires into your house. If that is what is happening the device would sense the increasing electrical flow which builds over time. If you get an E3 warning, you may have time to get to your breaker box. He says if it is an E1 or E2 event, you won’t have time to get to your breaker box, however you would know it is an EMP rather than just a local power outage.

@empdoctor I wrapped electronics boxed (in original packaging) with heavy duty aluminum foil and sealed with metal tape. Should I also put those packages (foil) in a galvanized trash can? Would I have to put plain cardboard inside the trash can first? Thanks in advance

[@disasterprepper]

If you've fully wrapped the box with heavy-duty aluminum foil, you should be fine. That provides about 50 dB of shielding (99.7% field reduction). If you do put things in a trash can, most people line the interior of the can to keep anything metal from touching the interior wall.

Wondering if you have any advice for EMP protection for people with implanted medical devices? My husband has a pacemaker and my brother-in-law has a LVAD device while he waits for a heart transplant. With what's going on with Ukraine, worrying about nuclear EMP! Recommendations appreciated! Thanks

[@davidg.johnson7574]

So low voltage alarm on your unit has nothing to do with an EMP surge, correct?

[@disasterprepper]

I've never been convinced that E3 would only result in overvoltage conditions. It could also cause currents to flow in ways that resulted in undervoltage conditions in some areas.

Dear Dr. Bradley, I have some metal oil barrels/drums, that I plan to use as Faraday cages for protection of electronics in case of a nuclear EMP. They are originally painted (blue). Will they still work as long as I take care of sand papering the connection between the top of the barrel and the lid to secure a good metal-metal connection as well as covering any seams? or will the (non-conductive) paint on the outside cause a worse shielding effect (as the garbage cans I have seen you use have been all metal on the outside)? Also, will a fridge and washing machine survive an EMP (they are not connected atm as I am off-grid living and my PV system off now)? Thank you for what you are doing, and God bless. Nikolaj in Denmark

[@disasterprepper]

The non-conductive paint on the body of the barrels won't hurt anything. You can certainly sand off the lip where the seal is to occur. Cover any seams with conductive tape too. Refrigerators and other appliances might or might not survive an EMP. Many of them have pretty sophisticated controllers that might be damaged. Being off grid certainly helps because it removes the E3 threat.

@@disasterprepper Thanks a lot for answering, I know you are busy, so I appreciate it a lot. Take care.

[@jevelwilson]

I would think by the time you hear the alarm, it is too late to run to your breaker panel.

[@disasterprepper]

The E1 and E2 will be over in microseconds, but the E3 surge (which is what is most likely to cause damage to things plugged in) occurs over minutes to hours, giving you the time needed to go flip the breaker.

[@tmt8425]

I’ve been following Dr Bradley for several years, and since I’m just a layman here is what I learned in layman terms. If any E1 or E2 event occurs and you are in the line of fire, it occurs so quickly that there is nothing you can do. But if you are not in the line of fire (an E3 event) you still have to be concerned about the pulse generated on the electrical grid even far away, bc an E1 or E2 causes a pulse to travel along the grid and it will build up over minutes or hours and damage your home even though you were not in the direct line of fire and the E1 or E2 event. In that case the alarm will go off and you may have time to flip your house main breaker. An EMP can get you in 2 ways: 1) the event occurs close enough to your home and the EMP does damage in a millisecond before you can do anything, but 2) even if you are not in direct line of fire, there will be a surge that travels along the electrical grid that spreads beyond the direct line of fire. If the alarm goes off in that situation, then flipping the breaker within a few minutes can save you stuff plugged in at your house. This part is just my guess: but I think many more people will suffer as the pulse travels along the grid effecting many more people who were in the direct line of fire. But if EMP goes off over your house there is nothing you can do. But the device will tell you it was an EMP and just not a local power outage. The device can give you hours to act on your plans before others figure out what is happening.

Very interesting product.

[@kenmarchlenski4477]

Hey Doc! Have you looked into : "Faraday Fabric Newbeau Radiation Shielding Fabric for Signal Blocking Fabric Shielding" ? IF so, what's your thoughts?

[@disasterprepper]

No, I haven't tested this particular cloth. I did test about 25 different cloths, and each has advantages and disadvantages, making them good for different uses.

[@kenmarchlenski4477]

@@disasterprepper Thank you for your time to answer. Will the ol Radio "On" inside a claimed EMP protection cloth be any kind of "test" of Mr. Regular Guy like me?

[@kenmarchlenski4477]

Here's my name on this comment. I like and appreciate you and your work. You're my Go-too EMP person. I ordered one of you EMP sensors a month ago (Feb. 24). HOW ARE THEY COMING AS FAR AS BEING READY TO SHIP? Is there anyway to contact you over sales?

[@marygallagher3428]

Looks like a great new product!

[@disasterprepper]

Thanks Mary. I hope you are well.

[@myballwilson]

Why not trigger a disarm of the main breaker as well as sound an alarm? If that would help in time take out the human element.

[@disasterprepper]

It's a possible future development. It's just much harder to do in a general way for everyone because there are many types of breakers.

[@morningdew2594]

@@disasterprepper Maybe look into most commonly used breaker and start there. Kind of like a standard in industry that most homes have. I'm by no means electronically inclined, but that would be my first guess as to where I'd start my project. Great concept.

[@gasman77]

I'm not an expert by any means but it seems like the most straightforward solution would be to keep replacement parts/phones etc in faraday cage, take your losses and replace what's fried afterward.

[@disasterprepper]

Yep, lots of people do this for smaller items.

[@lleweyriggs7065]

What's going to be around after an EMP?

[@iiinsaiii]

Wait… but if it was detected. That means it already happened. It’s too late to do anything. But if it gives you some time, then how long do you have to act? Seconds? Minutes or what???

[@BatmanBoss]

Thanks buddy
